PUMP, I

A Patented Jan. 1, 1907.

To all whom it may concern.-

Be it known that I, HARRY JONES, a citizen of theUnited States,residing atWashington, in the District of Columbia, have invented certain new and useful Improvements in Pumps, of which the following is a specification. L

My invention relates to an improvement in pumps; and it consists in the construction a n ngement of the several parts, which will be described in the specification, illustrated in the drawings, and particularly pointed out in the'clailns. I

The object of my invention is to provide a pump whichwill produce aconstantly-u ward movement of a stream of water-and de ivery thereof from the spout regardless of the depth of the well or the distance of the source ofsupply from the surface of the earth.

Another object of my invention is to utilire the compression and expansion of air so as to demonstrate its usefulness in raising a column of water to great heights, thus saving some of the cost of the elevation of the same. 1 A further, object of my invention is to so construct a ump that it shall be strong and durable, rea ly placed in position in a well, and easily understood and managed,

I accomplish these objects by the structure and the several parts thereof shown in the accompanying drawings, forming a part of my application, in which like letters refer to similar parts, and in which Figure 1 shows the portion of the ump usually above the earths surface, and l ig. 1 shows the parts of the pump in the well.

Referring to the drawings, A represents the pump, haying a superposed air-chamber A,

a spout a, and a handle a.

B re resentsthe well-pipe descendin into the we and B the pump-rod. At the ower end of the rod B is a plunger 12, moving in a cylinder 0, which is screw-threaded and secured at its upper and lower ends to-connections 0 and c. I

A valve 0" is provided in the lower end of cylinder C. The well-pipe B descendin into the well is secured to the cylinder 0, eing screw-threaded into connection 0. An airchamber D at its lower end is secured to the upper end of cylinder G in connection c and at its upper end is screw-threaded to the well-pipe B. r

E represents an air-pump, and E its connecting-pi e. The pipe E is connected to the chamber D at D. The air-chamber D and the pump E and pipe E will perform very important functions in the operation of this pump.

Heretofore attempts have been made to utilize air to aid in raising water from wells other sources of supply, but with indifferent success because of misunderstanding of the necessary mechanism to secure desired and beneficial results. In this application I show and describe means and mechanism the nature and character of the element or which do utilize the compressive and expansive qualities of air and do aid materially 111 raising the water in'connection with the other mechanism shown and described.

As heretofore stated, I desire to secure aconcharged from the spout a. At the same time water will also be forced into the airchamber D and the pipe E. On the next downstroke .of the plunger the water in the pipe E will be forced by the expansion and pressure of the air therein down through the opening D from the pipe E into the chamber D, and up and out of said chamber, and by the suction created in the pipe B up and out of the cylinder 0, thus forcing a contin-' uous stream out of the spout a. Thus the upward stroke of the plunger produces an upward stream of water, and on the down,

ward stroke of said plunger the compressed air in the pipe E expands and forces the water cushioned thereby up and out of the pump-spout, giving a continuous stream. This result will be obtained as long as the handle of the pump is operated. An airpump E is shown, and b it, if desired, a stronger-pressure of air in t e chamber D and pipe may be obtained.

Having thus fully described my invention and its operation, What I claim, and desire to secure by Letters Patent, is j 1. The combination with a pump having a .discharge- 'pe of an air-chamber c'ommumcating with said discharge-pipe at or near its connection with the pump throu h a passage charge-pi e and an air-chamber communithrough pipe, which passage terminates at the end remote from the pump-body in an annular Opening which surrounds the bore of the discharge-pipe.

2. The combination with a pump having a vertical discharge ipe of an air-chamber communicating said discharge-pipe at or near its lower end through a vertical passage which terminates at itslupper end in an annular opening which surrounds the bore of the discharge-plpe. y

3. The combination with a'pump provided with a reciprocating piston, and having a diseating with said discharge-pipe at a point near its connection with the pump-body a passage substantially parallel with said scharge-pipe, which passage terminates at the end remote from the pump-body in an annular opening which surrounds the bore of the discharge-pipe. v

4. The combination with a pump provided with a reciprocating piston, and having a 1' vertical discharge-pipe ofan air-chamber communicating with said discharge-pipe at or near its lower end through a vertica passage which terminates at its upper end in an annular opening which surrounds the bore of the discharge-pipe.

5. The combination with a pump provided with a conical head having an a1r chamber therein, and a concentric discharge-pipe of an air-chamber communicating with said dis charge-pipe at a point near its connection with the pump-body through a passage sub 35 stantially parallel with said discharge-pipe,

which passage terminates at the end remote from the pump-body in an annular opening which surrounds the bore of the dischargeby pipe.
